Description
Technical field
The present invention relates to field of mechanical technique, and in particular to a kind of plus guiding safety chuck.
Background technology
What common standard security collet leaned in the market is the frictional force that is generated between spring and steel ball to ensure that disk is being transported
It is not opened when row, but this frictional force is limited.Due to various reasons, disk can be in half-dozen in the process of running
The state opened, the self-locking inclined-plane dry friction with safety chuck is to generate a large amount of metal fillings.Common safety chuck is because have
Frictional force between spring and steel ball exists, and opens disk and wants prodigious power (if operator when the diameter of material is bigger
Hand to extend have an effect it is relatively difficult be just more difficult to open disk).The square chuck of standard should be driven and position again, every turn of collet one
A 90 degree of air-expanding shafts and dragging for collet will hit at mouth cooperation there are one altering, and gap can easily become larger in use.Gap is bigger
Material at runtime stationarity it is poorer alter hit it is just also big.
Therefore, present market is using directly safety chuck is pushed away, because it is all round that the problem of cooperation precision is most of, by riding
Key of joint transmits torque, the general trisection of junction of the edges of two sheets of paper pin.Junction of the edges of two sheets of paper pin is smaller and is trisection, this results in being put into air-expanding shaft
When on collet support mouth will to comparison fiducial axis can just be put into position, such relatively time-consuming of operation.Axis is bad, and to be put into position time-consuming
Laborious inefficiency, simultaneously as misalignment be easy to cause destruction cooperation precision of colliding with.
Invention content
The present invention provides safety chuck that is a kind of plus being oriented to, solves the problems, such as techniques discussed above.
The technical solution that the present invention solves above-mentioned technical problem is as follows:Safety chuck that is a kind of plus being oriented to, including chuck dress
It sets and air-expanding shaft, the chuck assembly includes chuck axis and chuck, described chuck axis one end is rotatably dispose on chuck assembly, separately
One end is equipped with the card slot being caught in for one end correspondence of the air-expanding shaft, and the card slot makes the gas along the radial opening of chuck axis
The corresponding one end of swelling shaft can be radially be caught in the card slot, the chuck is slidably arranged on the chuck axis, the card
Disk can be axially slided to the opening for covering the card slot and prevent air-expanding shaft from radially taking out, and the chuck axis is close to the inflatable
One end of axis, which is equipped with, is oriented to groove body, the inner cavity for being oriented to groove body and being equipped with cross section as equilateral triangle, and the two of the air-expanding shaft
End is respectively equipped with accurately to be put into the matched triangle guide pad of guiding groove body, described one end for being oriented to groove body auxiliary air-expanding shaft
Card slot.
The beneficial effects of the invention are as follows:The lumenal cross-section for being oriented to groove body is equilateral triangle, and described equilateral three
Angular wherein a line setting is in horizontal upper end and equipped with opening, the identical setting of the triangle guide pad, to which triangle is oriented to
Block, which can be efficiently put into, to be oriented in groove body.It is installed at triangle guide pad and the guiding groove body for installing chuck axis side additional on air-expanding shaft
Form guider.The auxiliary device only plays guiding role in upper and lower material, and transmission is with positioning or by the card of chuck axis
Junction of the edges of two sheets of paper pin in slot is completed with the matching grooves on the circular block of inflatable shaft end.The auxiliary device make place air-expanding shaft when only
Inflatable shaft end can be put by guider by the junction of the edges of two sheets of paper pin automatic in-position of general trisection by being substantially aligned with
Groove on circular block.The device so that material is more convenient more accurate, time saving and energy saving up and down;Reduction, which is collided with, improves entire safety clamp
The service life of head.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the safety chuck is directly to push away round safety chuck.
Advantageous effect using above-mentioned further scheme is:It is safer directly to push away safety chuck.Essentially consist in following advantages:
(1), the cooperation precision of disk and axis is more reasonable, disk and with axis sliding friction surface be all made of heat treatment grinding, that is, ensure precision
Increase service life again.Disk is more flexible, light in folding.The design position of safety switch is more reasonable, more effortless, more square
Just;(2), air-expanding shaft positioning is positioned using circular arc, the transmission of junction of the edges of two sheets of paper pin, material when rotated axis and collet to drag mouth always be circular arc
Contact;(3), structural symmetry is good, cooperation precision height operation is more stable.Have particularly with thin material and rotating speed Gao Shigeng excellent
Gesture.
Further, the center of the guide groove intracoelomic cavity is overlapped with the center of circle of the card slot.The guiding groove body with it is described
Card slot is positioned by the matching of the through-hole and straight pin that are correspondingly arranged.In addition, the guiding groove body is fixed by screws in
The side of the chuck axis.
Advantageous effect using above-mentioned further scheme is:It is described to be arranged concentrically the circle that ensure the inflatable shaft end
Type block can be accurately put into the round groove on the chuck axis, and the straight pin is easy to use, and dismounting is flexible, also makes institute
